I didn't like sound of Audionirvanas without baffle step circuit. I had them in adapted sony floorstanding enclosure, sound was harsh and bass nonexistant, although imaging was excellent. Once I added bsc, they sound much better. Now acoustic jazz music sounds beautiful, especially i like how Dave Brubeck's "In your own sweet way" album sounds. But it still feels like this speaker needs some equalization, I am going to try to equalize them with Behringer Ultracurve Pro DEQ2496.
I think these speakers are excellent for low-mid volume listening, can't crank them up though.
